Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of unit loading type soft packing seal device.
Background technique
In existing water pump product, because of its concrete applying working condition difference, what the axle envelope of most of water pumps adopted basically all is packing seal at present, and filler is divided into two kinds of forms, and a kind of is packing-type, and a kind of is the soft packing formula, and installation form is all basic identical.In the pump cover formula stuffing box body of water pump, a filler chamber is set directly; Earlier each parts of water pump and pump shaft, pump cover or the assembling of stuffing box body being accomplished during installation makes it form behind filler chamber's cavity installation packing or soft packing in the cavity again; Compress with Gland more at last, compress bolt locking behind the filler.Contact with pump shaft direct friction and sealing effect of the installation of this kind filler and adjusting, filler is not good, because of the narrow limitation of this kind filler mounting type.After water pump uses a period of time; Must be with pump shaft, pump cover or stuffing box body are all more changed water pump ability proper functioning, and in installation, maintenance, very inconvenient when changing filler; Therefore increase promptly that cost is not saved time again but also the proper functioning that influences water pump reduces its working life.
Summary of the invention
The purpose of the utility model is to overcome the deficiency in the problems referred to above, and a kind of unit loading type soft packing seal device is provided.
For solving the problems of the technologies described above; The technological scheme of the utility model is: a kind of unit loading type soft packing seal device; Comprise packaging case, axle sleeve, it also comprises outside thread round nut, locking card pad, packing ring, outside framework oil seal, the soft packing of mud shape, " O " type circle, flat key, Cock screw, plug, hex head bolt; Axle sleeve is inserted in the packaging case and its composition shipping container; There are outside framework oil seal, packing ring and outside framework oil seal in the inner chamber two ends of said shipping container and neutral position device successively, and shipping container, two outside framework oil seals and packing ring are formed filler collection dress chamber jointly; The outside thread round nut screws in the screw thread of packaging case and with outside framework oil seal and keeps certain axial clearance; The soft packing of said mud shape is infused in the filler collection through the hand-hole on the packaging case and adorns indoorly, is provided with plug in the hand-hole.
Offer six stopping locating slots on the end face of outside thread round nut, be provided with the location hex head bolt in the stopping locating slot.
The utility model is simple in structure, installation, maintenance is convenient succinct, good sealing effect, and this is novel to be independent sealed assembly, independently seals integral body as one after can adjusting separately and carries out can, installation, maintenance and replacing, very convenient, saves time, and saves cost.
Description of drawings
To combine accompanying drawing and embodiment below, the utility model will be further described.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the outside thread round nut structural representation of the utility model.
Fig. 3 is the locking card mat structure schematic representation of the utility model.
Embodiment
Like Fig. 1-shown in Figure 3, the utility model comprises: packaging case 1, axle sleeve 2, outside thread round nut 3, locking card pad 4, packing ring 5, outside framework oil seal 6, mud shape soft packing 7, " O " type circle 8, flat key 9, Cock screw 10, plug 11, hex head bolt 12～13, " O " type circle 14, stopping locating slot 15, tapped hole 17, pump shaft 18, connecting bolt 19, pump parts 20.Wherein the locking card pad is that 3, outside framework oil seal are that 2, plug are 4.
As shown in Figure 2, the end face of outside thread round nut 3 was last to be provided with six stopping locating slots 15.The stopping locating slot is provided with the location hex head bolt.As shown in Figure 3, locking card pad 4 is provided with through hole 16 and tapped hole 17.
In the utility model; Be adjusted into one to the assembling earlier of soft packing seal device and independently seal single unit system; Axle sleeve 2 is inserted in the packaging case 1; Guarantee that relative position forms shipping container, pack into successively in shipping container inner chamber two ends that form and neutral position respectively an outside framework oil seal 6, packing ring 5 and another outside framework oil seal make it form filler collection and adorn the chamber; Outside thread round nut 3 screws in the screw thread of packaging case 1; And maintain certain axial clearance with outside framework oil seal 6; The soft packing 7 of mud shape is injected the filler collection that forms through the hand-hole on the packaging case 1 and is adorned indoor; Stop up the hand-hole on the packaging case 1 respectively with 2 plugs 11, outside thread round nut 3 is compressed, mud shape soft packing 7 is to suitably tight power; 3 locking card pads 4 are packed on the axle 2 and are contacted with the end face of packaging case 1; Through through hole 16 locking locking card pads 4,3 hexagon head bolts 13 are inserted in the stopping room groove 15 on the end of outside thread round nut 3 through tapped hole 17 and locking with 3 hex head bolts 12; Respectively 2 plugs 11 are stopped up 1,3 Cock screw 10 of packaging case and insert on the axle sleeve 2, round section joint ring 8 is inserted in the axle sleeve 2, and round section joint ring 14 is inserted the place, other end of packaging case 1, makes it form an independently unit loading type soft packing seal device.The flat key 9 of on pump shaft 18, packing into; The unit loading type soft packing seal is put and whole is inserted in pump shaft 18 and flat key 9 box that matches through axle sleeve 2; Be connected with pump parts 20 and lock with connecting bolt 19, adjustment axle sleeve 2 behind the axial position on the pump shaft 18 with three Cock screws, 10 locking axle sleeves 2.
The utility model is simple in structure, and installation, maintenance is succinctly convenient, good sealing effect; Can also regulate the sealing load of mud shape soft packing; The sealing device is black box independently, the adjustment back be can assemble separately and can, installation, maintenance and replacing, very convenient, quick carried out as the sealing integral body of a uniqueness, and be to contact with axle sleeve; Do not protected axle because of the soft packing of mud shape contacts with axle, having reached saves time reduces cost and has prolonged pump working life.
